Installing Games on Samsung SGH-M620 (2007 Feature Phone)

You cannot install modern games. The SGH-M620 is a 2007 Java ME (J2ME) feature phone with:

• 2 MB internal memory (no card slot on some variants)
• 128×160 px screen, no touchscreen
• WAP 2.0 / xHTML browser—no app store

What Can Run

• .jar / .jad Java MIDlets (tiny 2D games: Snake, Tetris, Doom RPG, Tower Bloxx).
• Transfer via Bluetooth or USB (PC Studio 3) to "Other Files" → launch from Games & Apps.

Realistic Alternatives

• Dedicated retro handheld: Anbernic RG35XX, Miyoo Mini Plus ($50–$70) play GBA/PS1/N64 perfectly.
• Modern budget phone: Moto G Power, Galaxy A15 ($100–$150) run Play Store games.
• Java emulation on PC: KEmulator, FreeJ2ME for nostalgia.

The M620 is a museum piece—enjoy it as a caller/texting device.
